BRISTLE-BED FOR BRUSH-MACHINES.

To all whom it may concern:

' Be it known that. I, ANTHONY VANDER- van), a citizen of the United States, and resident of'Grend Rapids, in'the county of Kent and State of Michigan, have invented an Improved Bristle- Red for Brush Ma chines, of which the following, taken in connection with the accompanying drawings,

is a specification.

I n brush machines in which tufts of bristles are set in brush b anks, it is necessary 7 that a supply of bristles be had and that they be fed to the machine as required.

It is with the bristle supplying means that this invention is concerned, and it has for its purposes and objects to make a reservcir, storage compartment, or as it is known in the art, a bristle bed of new and im proved structure, which will hold a large supply of bristles, feed them to the machine in a new and advantageous manner, which will allow the insertion of an additional supply of bristles by an easy and cilicient method. which will allow the removal of any loose bristles in the bed quickly and readily, and which when the supply in the bed is nearly exhausted, will give notice of the fact by an automatic disconnection of certain parts of the device, rendering the feeding of the bristles thereafter practically ineffectual. All of these desirable features are incorporated together'with many others, in the structure illustrated in the drawings as one embodiment of my invention, and in which, 1

bundle receiving member, located back of the follower.

The brush machine is of thetype shown in my copending application, Serial No. 741,834; filed-Jan. 13, 1913, and it has cams 2 and 3, operating through arms 4 and 5 to work the staple guide and inserter portlons of the machine, said operations 00-. curring as described 1n sald application.

Feed wheel 6 having slot 7 is provided and 1s mounted so as to come at the open end of, the bristle bed 8, which is the subject matter of this invention. All of these cams,

arms, etc., are mounted on the frame 9 of the machine, and the bristle bed is also mounted on an upright 10 of the frame, being spaced some distance therefrom by the journal lug 11 as shown in Fig. 2. The bed comprises relatively stationary parts,

the base 12, side 13, and top 14 partially covering the space above the base Base 12 ;and top 14 are curved in outline and the side 13 is curved to correspond-fitting between the base and top and rigidly connecting them through the bolts 15, leaving an open side between them. In the open space so provided adjustable plates 16 are positioned and are adjustable toward and from each other by reason of the slots 17 formed 'in top H, through which thumb screws 18 are inserted and screwed into plates 16 thereby fixing them with respect to the top. This adjustment of the plates 16 is provided to allow for different lengths of bristles, which are to lie lengthwise between plates 16.

The feedwheel 6 is positioned at the Ifront of the bristle bed and immediately adjacent to the front open end thereof. Said :wheel, as described in my ,co-pending application, has rotary movement" backward through practically half a circumference,

then forward to initial position, the slot therein being in this manner, presented at the opening in the bristle bed and receiv- {ing bristles which on its return the wheel carries to the staple guide and delivers thereto. In order that the bristles shall be. always in shape to enter the slot I have provided a follower member 18 which lying back of the bristles is made use of to force the bristles forward and in contact with tl1e wheel whereby whenever the slot 7 is presented to the bristles, they will be :forced therein. This follower member coma a; v 1,070,861

prises in structure a body 19 and two extensions 20 integral therewith, making in ap ,pearance a fork as shown in Fig. 5. A handie 21 is riveted securely to the body of the follower, and is of use in operating the follow-*erdengthwise of its support as will be hereafter described. The ends of the extensions 20 are made pointed so as to easily pass through the loose bristles.

The body portion of the follower 18' is mounted in a support 22 lying'in a slottherein and secured by plates 23 which lie across the slot at either end thereof and are fastened by screws 24 to the support, binding the follower in the slot and securely holding it. At any time it is desired to move the follower with reference to the support, the screws may be loosened and the follower moved lengthwise of the support by means of the handle 21. The support 22 is pivotally mounted between itsv ends on a bolt 25 which is threaded into a lug inserted in the downward side extension 26 of the base 12. Connected with the support 22 and movable therewithis a grooved roller 27 having a notch 28 cut therein and shaped to receive the roller 29 mounted on the end of the member 30, which normally seats in the groove of roller 27 and which has attached thereto at its other end a weight cord 31, leading through an opening in the upwardly projecting lever to and over a pulley 33, a weight (not shown) being attached to the free end of the cord. Follower 18 being mounted in its support 22 extends through the base 12, the forked extensions 20 of the follower passing through slots 34 in the base. The normal tendency of the weight cord is to rotate the roller 27 ina clockwise direction, carrying the follower support 22 with it, and forcing the follower forward thereby pressing any bristles in front of the follower against the feed wheel. The location of the notch 28 in roller 27 is L such, however that when the follower comes in proximity to the feed wheel, that is when there are few bristles in front of the follower, the roller 29 and its supporting member 30 will disengage from notch 28 and the groove in roller 27, thereby taking away the force which normally operates the follower forward, and rendering the feed of the bristles into the slot of the feed wheel practically inoperative. Parts 30 being free will be drawn back until it contacts with lever 32 by which it is stopped. A handle extending laterally from member 30 is used to return theroller to notch 28 and the part 30 to the groove in roller 27. The slots 34 in base 12 extend nearly to either end of the base and allow the follower extensions 20 to operate through a wide arc.

Projecting upwardly from. the base 12, at either side of the slots 3%. and downwardly from the top 1 f substantially opposite to these on the base, are ribs 36 which serve to keep the bristles from bearing against the whole inner surfaces of base 12 and top plate 14, thereby reducing friction and facilitating the movement of the bristles toward the feed wheel. Toward the front of the bristle bed, the lower ribs are discontinued and between their ends there is mounted on a pivot 37, the plate 38, its

)ivotal mountin allowin it to swim toward the top 1 1. Mounted on the same pivot 37 and passing under plate 38 is a lever 39 which extends beyond plate 38 and is bent upwardly, carrying at its free end a'small roller 40, which lies against a cam 41 secured to and movable with the feed wheel 6. The cam is so shaped that on the backward movement of the feed wheel. it elevates the roller 40 and the lever attached thereto, thereby carrying plate 38 toward the top 14: and further compressing the bristles positioned therebetween so that when the slot 7 is presented to the-bristles'they .will be under considerable pressure and will the more freely enter. On the return of the feed wheel, this pressure will be relieved, allowing the follower to force the bristles forward.

The operation of the device so far as described will now be readily apparent. Starting with the bed full or nearly full of loose bristles in front of the follower fork extensions 20, substantially as shown in Fig.

1, the tension of cord 31 imparted to roller 29 serves to. force the follower against the bristles thereby pushing them forward to the open end of the bed against the feed wheel. On the backward throw of the feed wheel, the plate 38 is elevated and the bristles next to the feed wheel are compressed to a still greater extent so that when the slot 7 comes into position to receive bristles, they are under their greatest pressure and readily enter the slot under the influence thereof] This operation may be repeated until the supply of bristles in the bed gets low, at which time the notch 28 in roller 27 has gone far enough that the tangential force exerted on the roller 27 against the shoulder of the notch serves to draw the roller 29 from the notch, the shoulder of the notch having become so positioned that it will allow this, freeingthe follower from the force that impels it forward, and allowing it to be easily returned to original position, the member 30 and roller 29 being replaced as described heretofore.

Bristles in their loose state are not easy to handle and cause considerable trouble if it is necessary to so handle them. I have provided means whereby the bristles need to be manually handled only in bundles, avoiding the trouble and annoyance stated. To this end, the top 14 does not,extend over the whole of the bed but only about half way as shown, leaving an open trough back of the one end, the curved prongs or forks 44,

said prongs extending in the same direction as the body 43- 'for' a" distance then being bent .at an curved substantially in the arc of a circle. At its other end the body 43 is formed into a journal by means of Whichthe device is pivotally attached to the follower support 22, having a loose connection therewith so as to be easily movable with respect thereto. The prongs or fork members 44 extend through-the slots'34 in the base 12, and the curved portions thereof come to about the outer edge of the spacing plates 16. In normal position, this holding orretaining device rests on the bottom of the slots 34 and is in position to receive the bundles of bristles. This position is indicated by dotted lines in Fig. 6 and in full lines in Fig.

1. After the bundles of bristles have been dropped in and are resting on member 42, the cord that is passed around them is cut placing them in a loose state above the retaining member. When the supply of bristles in front of the follower gets low, the member 42 may be turned into the position indicated in full lines in Fig. 6, and the bristles carried on said member will be carried upward and over against, the :back of. the follower. the follower may be carried along the slot By loosening the screws 24,

in the follower support 22 until the fork extensions 20 thereof are below the bottom ribs 36 upon which the support 22 and follower may be turned backward to such 'position that when. the-follower is returned to normal place in its support, it will lie back of the bristles. This is indicated in the dotted line position of the follower in Fig.

-6. The "parts 44 are spaced far enough and they are to be removed, the screws 24 are loosened and the follower drawn back alongthe slot'in the'follower sup ort 22 until it is clear of the bristles and t en the follower support is turned forward until angle thereto and d the follower is in place to be'inserted in the bristles at the extreme forward portion of the bristle bed. The follower is then pushed into its normal place in the follower support, the pointed ends of parts 20 allowing this, when the loose bristles will be back of the follower. Upon turning the follower backwardly the loose bristles will be carried with it and will fall on the retaining member. A cord, indicated by numeral 45 may then be passed back of the bristles through a slot 46 cut in the base 12 for that purpose, and the loose bristles bound into a bundleafter which it may be lifted from the bed and other bristles inserted. When these operations are gone through with, the roller 29 and part 30 may be disconnected from the rest of the device, handle 35 readily permitting such manipulation, and they can be y returned after the device is in shape to feed bristles to the machine.
